Description

Technical Field

[0001] This utility model relates to the field of teleprompter technology, and more particularly to a medium-free holographic projection teleprompter. Background Technology

[0002] As an auxiliary tool, teleprompters help speakers convey information accurately and flawlessly while maintaining fluency and mental agility, whether in live television broadcasts, large conferences, or online speeches. With technological advancements, teleprompters have evolved from the initial manual paper scrolls to today's digital and intelligent devices capable of real-time editing and automatic scrolling.

[0003] Currently, most existing teleprompters can only play the prompts directly on the screen or project the text and images. They are complicated to use, and operators cannot stand for long periods of time without proper support. After a period of use, the teleprompters are prone to damage. Utility Model Content

[0004] One objective of this invention is to provide a medium-free holographic teleprompter that features a user-friendly design, simple operation, and safety.

[0005] To achieve at least one of the above objectives of this utility model, the main body has an outer shell and a base. The cross-section of the inclined top surface and the vertical extension of the outer shell forms at least two handles, which can provide a comfortable support for the user's hands.

[0006] According to one embodiment of the present invention, the main body further includes a transmission area, an air inlet, and an air outlet; a medium-free holographic projection module, which is installed on the main body, and the image of the medium-free holographic projection module is displayed through the main body in the transmission area of ​​the main body; a snap-fit ​​device, which is installed on the main body; and a heat dissipation assembly, which includes a cooling component and a fixing component, wherein the fixing component is installed on the main body, the cooling component is installed on the fixing component, and the cooling component includes at least one cooling fan.

[0007] With the above solution, when the cooling fan starts, the air drawn in from the air inlet can expel the heat inside the body from the air outlet, thereby reducing the internal temperature of the body and improving its service life.

[0008] According to one embodiment of the present invention, the latching device includes a housing, a driving member, a moving member, and a resetting member. The housing is fixedly installed on the main body, the moving member is movably installed on the housing, the driving member is installed on the moving member, and the resetting member is installed at the end of the moving member away from the driving member. The driving member includes a pressing block, which is installed on the moving member. The pressing block includes a sliding part, a pressing part, and a guiding part. The sliding part, the pressing part, and the guiding part form a sliding space. The resetting member moves along the sliding part, the pressing part, and the guiding part within the sliding space. The moving member includes a moving plate and a guide block, which is installed on the moving plate. The resetting member includes a spring and a guide rod, which is installed on the moving member. One end of the guide rod is installed on the spring, and the other end is slidably installed on the moving plate.

[0009] With the above scheme, when the operator applies a thrust to the driving component, the driving component pushes the moving component to move, and the moving component moves towards the side closer to the reset component. At this time, the driving component separates from the body. When the driving component loses its thrust, the reset component pushes the moving component to move towards the side closer to the driving component, so that the driving component is engaged with the body, thereby ensuring the airtightness of the top of the body and the optical waveguide plate.

[0010] According to one embodiment of the present invention, the cooling component includes a plurality of heat sinks and a heat-conducting plate, wherein the plurality of heat sinks are mounted on the heat-conducting plate.

[0011] Through the above scheme, after the heat-conducting plate absorbs heat, it is transferred to the heat sink to dissipate the heat from the power supply unit and the control unit.

[0012] According to one embodiment of the present invention, the medium-free holographic projection teleprompter includes a power supply unit and a control unit, which are installed on the main body. The power supply unit, the control unit, the medium-free holographic projection module, and the heat dissipation component are electrically connected.

[0013] Through the above solution, the power supply unit can provide stable voltage and current to the control unit, the medium-free holographic projection module, and the heat dissipation component.

[0014] According to one embodiment of the present invention, the cooling component further includes a temperature sensor, which is mounted on the heat-conducting plate.

[0015] The above method is used to monitor the temperature of the heat-conducting plate. When the temperature of the heat-conducting plate rises to a set value, the cooling fan will be driven to rotate to cool the heat-conducting plate.

[0016] According to one embodiment of the present invention, the heat sink is made of aluminum or alloy material, and the heat dissipation groove of the heat sink is facing the cooling fan and the air inlet.

[0017] With the above solution, the heat sink is made of aluminum or other alloy materials, which can quickly conduct the heat generated by the control unit and power supply during operation to the heat sink. Moreover, the heat dissipation grooves of the heat sink are directly opposite the air inlet, which can accelerate the heat dissipation speed of the heat sink and improve the heat dissipation efficiency of the body.

[0018] According to one embodiment of the present invention, the fixing member includes a mounting bracket, which is fixed to the bottom of the body.

[0019] The above solution facilitates the fixing of components inside the main body.

[0020] According to one embodiment of the present invention, the transmission area is inclined, and the inclination angle is 20°-35°.

[0021] With the above solution, the operator's eye coverage angle when watching the video is 45° to 60°. At this time, when the main body's transmission area is tilted, the angle between the projected image and the horizontal plane can also reach 50°-80°, which falls exactly within the field of view of the human eye looking down. Thus, the human eye only needs to look down to effectively observe the image, reducing the effort required for the user to observe the image and greatly improving the user experience.

[0022] According to one embodiment of the present invention, the medium-free holographic projection module includes a display screen fixed in the body and a detachably connected optical waveguide plate located in the projection area.

[0023] The above method can reproduce a 100% aberration-free real image in three-dimensional space that can be directly observed with the naked eye.

[0024] The advantages of this utility model are that it has a user-friendly design, is easy to operate, and is safe.

[0025] The further objectives and advantages of this utility model will become fully apparent from the following description.

[0026] These and other objects, features and advantages of this utility model will be fully realized through the following detailed description. Attached Figure Description

[0034] The preferred embodiments described below are merely examples, and other obvious variations will be apparent to those skilled in the art. The basic principles of this invention as defined in the following description can be applied to other implementations, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of this invention.

[0035] Those skilled in the art should understand that in the disclosure of this utility model, the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as a limitation of this utility model.

[0036] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0037] Refer to the instruction manual. Figures 1 to 6 A preferred embodiment of the present invention, a medium-free holographic projection teleprompter, will be described in detail below:

[0038] The medium-free holographic teleprompter includes a body 10, which has a housing 11 and a base 12. The top surface of the housing 11 is inclined and the cross section of the vertical extension forms at least two handles 13, which can provide a comfortable support for the user's hands when the operator stands in front of the medium-free holographic teleprompter to give a speech.

[0039] Furthermore, the body 10 is integrally stamped, which improves the structural strength of the body and makes it more durable.

[0040] Specifically, the body 10 further includes a medium-free holographic projection module and a heat dissipation assembly 20. The body 10 has a transmission area 16, an air inlet 14, and an air outlet 15. The medium-free holographic projection module is installed on the body 10 and projects a display through the transmission area 16. The heat dissipation assembly 20 includes a cooling component 21 and a fixing component 22. The fixing component 22 is installed on the body 10, and the cooling component 21 is installed on the fixing component 22. The cooling component 21 includes at least one cooling fan. When the cooling fan is started, air is drawn in from the air inlet and the heat inside the body 10 is discharged from the air outlet 15, thereby reducing the internal temperature of the body 10.

[0041] Specifically, the medium-free holographic teleprompter includes a power supply unit and a control unit, which are mounted on the main body 10. The power supply unit, the control unit, the medium-free holographic projection module, and the heat dissipation assembly 20 are electrically connected. This configuration allows the power supply unit to provide stable voltage and current to the control unit, the medium-free holographic projection module, and the heat dissipation assembly 20.

[0042] Furthermore, the power supply unit includes a battery and a charging interface. The battery is installed on the main body 10, and the charging interface is installed on the bottom side of the main body 10 and connected to the outside. The battery and the charging interface are electrically connected, and the battery is electrically connected to the control unit. The control unit includes a controller, a button, and an audio input terminal. The controller is installed on the main body 10, and the button and the audio input terminal are both located on the main body 10. The audio input terminal can be connected via a USB flash drive or via Bluetooth. The controller, the button, and the audio input terminal are electrically connected. The audio input terminal allows the operator to easily import the display content of the screen, and the button can switch the content played on the screen.

[0043] Specifically, the cooling component 21 includes a plurality of heat sinks 211 and a heat-conducting plate 212. The plurality of heat sinks 211 are mounted on the heat-conducting plate 212. The power supply unit and the control unit are mounted on the heat-conducting plate 212. After absorbing heat, the heat-conducting plate 212 transfers it to the heat sinks 211 to dissipate the heat generated by the power supply unit and the control unit during operation.

[0044] Furthermore, the cooling component 21 also includes a temperature sensor 213, which is installed on the heat-conducting plate 212 to monitor the temperature of the heat-conducting plate 212. The temperature sensor 213 is electrically connected to the control unit. When the temperature of the heat-conducting plate 212 rises to a set value, it will drive the cooling fan to rotate to cool the heat-conducting plate 212.

[0045] It is worth mentioning that the plurality of heat sinks 211 are made of aluminum or other alloy materials, and the heat dissipation grooves of the heat sinks 211 are directly facing the cooling fan and the air inlet 14.

[0046] With this configuration, the heat sink 211 is made of aluminum or other alloy materials, which allows the heat generated by the control unit and power supply unit during operation to be quickly conducted to the heat sink 211 through the heat conduction plate 212. Moreover, the heat dissipation groove of the heat sink 211 is directly opposite the air inlet 14. The cooling fan can draw in air from the air inlet 14 to accelerate the heat dissipation speed of the heat sink 211, and then exhaust it through the air outlet 15, thereby improving the heat dissipation efficiency of the heat dissipation assembly 20.

[0047] Furthermore, the fastener 22 includes a mounting bracket 221, which is fixed to the bottom of the body 10.

[0048] To ensure the airtightness of the interior of the body 10 and the opening and closing of the top of the body 10, a latching device 30 is also provided in the body 10. The latching device includes a housing 31, a driving member 32, a moving member 33, and a resetting member 34. The housing 31 is fixedly installed in the body 10, the moving member 33 is movably installed in the housing 31, the driving member 32 is installed in the moving member 33, and the resetting member 34 is installed at the end of the moving member 33 away from the driving member 32. When the operator applies a pushing force to the driving member 32, the driving member 32 pushes the moving member 33 to move, and the moving member 33 moves towards the side closer to the resetting member 34. At this time, the driving member 32 separates from the body 10. When the driving member 32 loses its pushing force, the resetting member 34 pushes the moving member 33 to move towards the side closer to the driving member 32, so that the driving member 32 is latched into the body 10.

[0049] Specifically, the driving member 32 includes a pressing block 321, which is mounted on the moving member 33. In this embodiment, the moving member 33 can be implemented as a moving plate. The pressing block 321 and the moving plate are integrally formed. The pressing block 321 includes a sliding part 3211, a pressing part 3212, and a guiding part 3213. The sliding part 3211, the pressing part 3212, and the guiding part 3213 form a sliding space 3214. The resetting member 34 moves along the sliding part 3211, the pressing part 3212, and the guiding part 3213 within the sliding space 3214.

[0050] Furthermore, the movable member 33 also includes a guide block 331, which is located in the same vertical plane as the pressing portion of the pressure block 321. The guide block 331 has a V-shaped cross-section, and its opening is relative to the pressing portion 3212 of the pressure block 321. Similarly, the sliding space 3214 has a V-shaped cross-section.

[0051] Furthermore, the reset member 34 includes a spring 341 and a guide rod 342. The spring 341 is mounted on the moving member 33, and one end of the guide rod 342 is mounted on the spring 341, while the other end is slidably mounted on the moving plate.

[0052] It is worth mentioning that when the pressure block 321 is pressed down, the guide rod 342 slides along the sliding part 3211 to the pressing part 3212. Under the action of the pressing part 3212, the guide rod 342 is pushed to the guide block 331. At this time, the moving plate moves towards the side closer to the spring 341 and squeezes the spring 341. The guide rod 342 is located in the sliding space 3214 formed by the sliding part 3211 and the pressing part 3212. The pressure block 321 is separated from the body 10, and the operator can open the top of the body 10.

[0053] When the pressure block 321 loses external thrust, the spring 341 pushes the moving plate to move away from the spring 341. At this time, the guide rod 342 moves along the inclined surface of the guide block 331 to the lowest point of the opening of the guide block 331, and the pressure block 321 is engaged with the body 10.

[0054] When the operator presses the pressure block 321 again, the guide rod 342 slides along the guide block 331 toward another inclined surface and moves toward the guide part 3213. When the pressure block 321 is pressed down to separate from the body 10, the guide rod 342 is located on the side close to the guide part 3213 and the pressing part 3212.

[0055] When the pressure block 321 loses external pressure again, the spring 341 pushes the moving plate to move, and the guide rod 342 moves along the guide part 3213 to the side of the guide block 331 away from the pressure block 321. At this time, the pressure block 321 is close to the body 10, and the body 10 is closed.

[0056] When the pressure block 321 is pushed again, the pressure block 321 drives the moving plate to move. The guide rod 342 is located in the sliding space 3214 between the sliding part 3211 and the guide part 3213, and moves back and forth in this way to realize that the buckling device 30 opens or closes the body 10.

[0057] Furthermore, the tilt angle of the transmission zone 14 of the body 10 is 20°-35°.

[0058] This configuration allows the operator's eye to be covered at an angle of 45° to 60° when watching the video. At this angle, with the transmission area 16 tilted, the angle between the projected image and the horizontal plane can reach 50° to 80°, which falls within the field of view of the human eye looking down. Thus, the human eye only needs to look down to effectively observe the image, reducing the effort required for the user to observe the image and greatly improving the user experience.

[0059] Specifically, the medium-free holographic teleprompter also includes a medium-free holographic projection module, which includes a display screen and an optical waveguide plate. The display screen is tilted and mounted on the mounting bracket 221, and the optical waveguide plate is tilted and mounted on the top of the main body 10. The display screen is electrically connected to the control unit, and the content played on the display screen can be switched by controlling the control unit. It should be noted that the setting of the display screen is related to the setting of the optical waveguide plate. That is, when the optical waveguide plate is set horizontally, the tilt angle of the display screen needs to be adjusted to achieve a better imaging effect; and the correspondence between the display screen and the final aerial imaging is axially symmetric about the optical waveguide plate.

[0060] Furthermore, the tilt direction of the display screen can be set to form a certain angle with the horizontal plane according to the display needs, so that the light emitted by the display screen can illuminate the light waveguide plate.

[0061] It is worth mentioning that the optical waveguide plate is a microchannel matrix optical waveguide plate, which uses the principle of optical field reconstruction and optical micromirror structure to replicate the optical field. It can reproduce a 100% aberration-free real image in three-dimensional space that can be directly observed with the naked eye.

[0062] Furthermore, the optical waveguide plate is detachable. The first end of the optical waveguide plate is rotatably connected to one side of the top opening of the main body 10, and the second end of the optical waveguide plate covers the latching device 30 on the top opening of the main body 10 away from the first end. This facilitates opening and closing the top of the main body, making operation convenient.

[0063] With this setup, when the power is connected or the battery is powered, the operator turns on the switch and presses the button on the control unit to control the mediumless holographic projection module to play relevant prompts or content.

[0064] Those skilled in the art should understand that the embodiments of the present invention described above are merely examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been shown and explained in the embodiments. Without departing from the described principles, the implementation of the present invention may have any modifications or variations.
